No, a lower angle of elevation from the Sun does not directly correspond to a bigger wavelength. The angle of elevation refers to the height of the Sun above the horizon as observed from a particular location on Earth. It is a measure of the Sun's position in the sky relative to an observer.
The wavelength of light, on the other hand, refers to the distance between successive peaks or troughs of a wave. It is a property of electromagnetic radiation and determines its color or frequency. The wavelength of light is not directly influenced by the angle of elevation.
However, it's worth noting that when sunlight passes through Earth's atmosphere at a lower angle, such as during sunrise or sunset, it has to travel through a larger portion of the atmosphere. This can result in more scattering and absorption of shorter wavelengths, particularly blue and green light, by the Earth's atmosphere. As a result, the remaining sunlight that reaches an observer at a lower angle of elevation can appear more reddish or have a longer effective wavelength. This phenomenon is responsible for the warm colors often seen during sunrise or sunset.
